No difference from the batch you grabbed and the latest one that I made up. I just had more made is all.
For those who don't know about the dreaded 2nd gear pop out, this detent basically allows for deeper engagement of the operating sleeve to the gear face. This gives a better grip to the dog ring and help prevent pop out.
If there is too much damage already though, you will need a rebuild which I can help with too if you need someone to do it.
Feel free to give me a call.
